[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0019] Figure 1 This is a flowchart illustrating the vehicle-mounted coffee machine control method provided by the present invention.

[0020] Figure 2 This is an electrical schematic diagram of a vehicle-mounted coffee machine, which is part of an embodiment of the present invention.

[0021] Figure 3 This is a schematic diagram illustrating the intelligent brewing operation principle of the coffee machine according to an embodiment of the present invention. Detailed Implementation

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0024] How a capsule coffee machine works: The user inserts a coffee capsule into the machine's designated slot. Water heating: An internal heater heats the water in the tank to a suitable temperature (usually around 92°C). High-pressure extraction: A pressurized water pump pressurizes the hot water and injects it into the capsule through a needle hole at the bottom. The high-pressure water flows into the coffee grounds, extracting the coffee. This process typically involves building pressure inside the capsule until the foil seal breaks, allowing the coffee to flow out. Enjoying the coffee: The extracted coffee is poured directly into a cup or other container, and the user can then enjoy fresh coffee.

[0025] Most existing coffee machines use steam boilers to heat coffee, which presents several problems that need to be addressed: the coffee is not heated properly by steam, the brewing head spews steam, and the machine makes noise. If the coffee flow rate is too slow during extraction, it may be due to too much coffee grounds, too high a pressure, or coffee grounds that are too fine. If the coffee flow rate is too fast during extraction, it may be due to too little coffee grounds, too low a pressure, coffee grounds that are too coarse, or uneven steam discharge from the steam wand.

[0026] While the car is in motion, it's inconvenient for the driver to operate the in-car coffee machine. Furthermore, making coffee to one's liking requires inputting numerous parameters, making the process too cumbersome and potentially dangerous. Additionally, selecting the correct operating parameters takes a considerable amount of time, preventing the coffee from being prepared quickly.

[0027] This invention connects a car coffee machine to the vehicle's central control system, utilizing the system's voice interaction function to control the machine. Since voice input requires specific coffee preparation information, such as coffee type and sugar content, typically the user needs to input all information via voice before the machine can start. This invention analyzes keywords, categorizing them into coffee keywords, coffee type keywords, and coffee / sugar keywords. When the user's voice command only includes the "coffee" keyword, the machine immediately starts heating water and waits for the specific coffee type and sugar content. This saves time; while the user selects the coffee type and sugar content, the machine has already begun heating water. Furthermore, the vehicle's central control system simultaneously acquires the machine's status information and guides the user through voice and the interactive interface, providing a better user experience.

[0028] This invention provides a vehicle-mounted coffee machine control device. It stores the vehicle-mounted coffee machine's operating data, including brewing data for controlling coffee brewing, in a data storage device. An ARM central processing unit controls the vehicle-mounted coffee machine's operation, reading brewing data from the data storage device to control the brewing process. A microwave heating module heats water in a microwave-heated water tank. A temperature sensor detects the temperature of the microwave-heated water tank and feeds it back to the ARM central processing unit for controlling the heating operation. An interactive module enables human-machine interaction, controlling the vehicle-mounted coffee machine's operating status and displaying its status information. Finally, it connects to the vehicle's central control system via a CAN bus interface to control the vehicle-mounted coffee machine's operating status.

[0029] In one embodiment, the microwave heating module of this invention includes: a microwave control module, a power drive circuit, a current transformer, and a microwave magnetron. The microwave control module is used to control the power drive circuit to turn on and off, and to input control signals to the current transformer to transmit current to the microwave magnetron for heating.

[0030] In one embodiment, the interactive module of this invention includes: control buttons, electrically connected to an ARM central processing unit, for controlling the operating status of the vehicle-mounted coffee machine; and a TFT display screen, electrically connected to the ARM central processing unit, for displaying the operating status information of the vehicle-mounted coffee machine.

[0031] Reference Figure 2 In one specific embodiment, the vehicle-mounted coffee machine control device of the present invention comprises an ARM central processing unit, a data storage device, a microwave control module, a power drive circuit, a current transformer, a microwave magnetron, a temperature sensor, a coffee cup, a microwave heating water tank, a TFT display screen, control buttons, and a CAN bus interface.

[0032] Reference Figure 3 The coffee brewing principle of the vehicle-mounted coffee machine control device of this invention is as follows: It consists of a microwave heating water chamber, a microwave magnetron, a micro water pump, a water tank, and a coffee cup. A coffee capsule is installed on the top of the coffee cup; the micro water pump starts to pump clean water from the water tank into the microwave heating water chamber; the microwave magnetron is controlled to start working, heating the microwave heating water chamber to a temperature of 90~93°C; the optimal temperature for brewing coffee is 90~93°C hot water, which is then injected into the coffee capsule by the micro water pump; the hot water flows through the coffee capsule into the coffee cup, completing the coffee brewing process.

[0033] Reference Figure 1 The present invention provides a control method for the device of the present invention, comprising the following steps:

[0034] S100: Obtain user voice command information through the vehicle's central control system, and analyze the user voice command information to obtain keywords; the keywords include coffee keywords, coffee type keywords, and coffee milk candy keywords.

[0035] S200: When the user's voice command information includes coffee keywords but does not include coffee type keywords and coffee milk candy keywords, generate a first control command and send it to the in-vehicle coffee machine; obtain the status information of the in-vehicle coffee machine, and display coffee making instruction information on the vehicle's central control system interactive interface according to the status information; generate and output the first voice interaction data according to the status information; determine the coffee type information and coffee milk candy information based on the user's interaction operation and send them to the in-vehicle coffee machine.

[0036] S300: When the user's voice command information includes coffee type keywords but does not include coffee milk candy keywords, generate a second control command based on the coffee type keywords and send it to the in-vehicle coffee machine; obtain the status information of the in-vehicle coffee machine, display coffee making instructions on the vehicle's central control system interface based on the status information; generate and output second voice interaction data based on the status information; determine the coffee type information and coffee milk candy information based on the user's interaction operation and send them to the in-vehicle coffee machine.

[0037] S400: When the user's voice command information includes keywords for coffee type and keywords for coffee milk and sugar, a third control command is generated based on the keywords for coffee type and coffee milk and sent to the vehicle coffee machine.

[0038] S500: When the vehicle-mounted coffee machine receives the first control command, it performs the water heating operation and waits to receive coffee type information and coffee milk sugar information; when the vehicle-mounted coffee machine receives the second control command, it performs the water heating operation and determines whether to perform the milk foam heating operation according to the second control command, and waits to receive coffee milk sugar information; when the vehicle-mounted coffee machine receives the third control command, it determines the coffee type information and coffee milk sugar information according to the third control command.

[0039] In one specific embodiment, the vehicle's central control system receives the user's voice command: "Make a cup of coffee." The system analyzes and recognizes that the voice command contains the keyword "coffee," but not keywords related to coffee type or coffee / sugar. After recognizing the "coffee" keyword, a first control command is sent to the in-vehicle coffee machine, instructing it to begin water dispensing and heating while awaiting information on the coffee type and sugar. Simultaneously, the system obtains the status information of the in-vehicle coffee machine and determines whether it can make a coffee type requiring milk, such as a latte, based on the remaining milk amount. Based on the current status information of the in-vehicle coffee machine, it generates the types of coffee that can be made and generates corresponding voice interaction data: "Please select a coffee type, for example: [coffee name]." The types of coffee that can be made are displayed on the interactive interface of the vehicle's central control system. By receiving the user's voice message "Latte" or by clicking "Latte" on the interactive interface, the coffee type information is confirmed, and a second control command is sent to the in-vehicle coffee machine, which begins heating the milk. The interactive interface displays coffee / sugar selection information, including specific parameters for making milk foam, and the coffee / sugar information is confirmed based on the user's operation. Once the in-vehicle coffee machine has completed the water heating process and confirmed the coffee type and milk / sugar information, it begins a constant water pouring process to produce the coffee the user needs.

[0041] In some embodiments, the method of the present invention includes: S700, after the vehicle-mounted coffee machine completes the water heating operation and determines the coffee type information and coffee milk sugar information, it controls the water pump to start a constant brewing control operation. The constant brewing control operation includes: after the water pump performs a single-step water injection operation, measuring the water injection flow rate; when the water injection flow rate is greater than the maximum water injection flow rate threshold, controlling the water pump to reduce the water injection flow rate; when the water injection flow rate is less than the minimum water injection flow rate threshold, controlling the water pump to increase the water injection flow rate.

[0042] In some embodiments, the method of this invention includes: S800, analyzing historical brewing data, analyzing historical data of constant brewing control operations for different coffee types, obtaining water pump operating status data when a constant water flow rate is achieved, clustering the water pump operating status data, obtaining and removing outliers, and obtaining standard water pump operating status data corresponding to different coffee types; the coffee type data includes coffee variety and grind size; when starting the constant brewing control operation, setting the initial operating state of the water pump according to the standard water pump operating status data.
